Fortunately, jQuery provides a built-in utility function. $ getScript () provides us with this method. To implement the dynamic functions of the webpage. Let's take a look at the syntax of this function:
$. GetScript (url, callback)
Obtains the script specified by the url parameter and sends a GET request to the specified server.
Parameters
URL () to obtain the URL of the script file.
Callback (Function) optional functions call the functions in the script file after loading
The specific implementation process is
Load text from resource
| If the string is successful
Returns an XHR instance to obtain the script.
How to use it? See the following method.
Create a new. js script file
Copy codeThe Code is as follows:
Var testVar = 'new JS loaded! ';
Alert (testVar );
Function newFun (dynParam)
{
Alert (You must passed '+ dynParam + 'as parameter .');
}
HTML code
Copy codeThe Code is as follows:
<Html>
<Head>
<Title> $. getScript Example </title>
<Script type = "text/javascript" src = ".../jquery. js"> </script>
<Script type = "text/javascript">
$ (Function ()
{
$ ('# LoadButton'). click (function (){
$. GetScript ('new. js', function (){
NewFun ('"Checking new script"'); // This function is in new. js. click it to run this function.
});
});
});
</Script>
</Head>
<Body>
<Button type = "button" id = "loadButton"> Load </button>
</Body>
</Html>
In the above Code, we create a new. js script file and call it when the button function is triggered in the body part. The advantage of doing so is to reduce the pressure on the server, which is highly recommended.
